Research on Network Protocol Fingerprint Recognition Based on Wavelet Analysis

At present, wavelet analysis is an active and rapidly developing domain in the field of signal information acquisition and processing (particularly in failure diagnostic analysis and detecting technology), and it is an international research hotspot. It has double significance of both profound theory and wide application. The authors conduct the research of network protocol fingerprint recognition based on wavelet analysis, which decomposes the primary signal to multi-frequency signal through wavelet transformation, decomposes the signal in the tower pattern, calculate and obtain all the related Wi information and pick up the characteristic information of the fingerprint. This article has proposed the detecting method and the system structure of fingerprint recognition, and has made a beneficial attempt to solve the problem of network security that is increasingly serious day by day.
